PAPER-CARRIAGE FOR TYPE-PRINTING MACHINES AND MECHANISM FOR CONTROLLING SAME.

SPECIFICATION forming part of Letters Patent No. 711,154, dated October 14, 1902. applicant fue@ June 1,1901. seralnataesa (ramdam T all whom, it may concern:

Be it known that I, ROBERT A. FOWDEN, a

citizen of the United States, residing at the city of Philadelphia, in thecounty of Phila- .5 delphia and State of Pennsylvania, have invented certain new and useful Improvements in Paper-Carriages for Type-Printing Machines and Mechanism for Controlling the Same, of which the following is a specificaro tion.

My invention i relation toan improved carriage for holding, feeding, shifting, and otherwise automatically controllingthe paper of a type-printing machine during the operation of the same, and in such connection it relates to the construction and arrangement of the carriage and of the mechanism controlling the same.

In type-writing, type-printing, and print- 2o ing-telegraph machines or machines of analogous construction and use it is essential that the paper and its carriage be shifted step by step laterally as the paper receives the imprint of each type or character, that the paper he fed at the end of each line or portion of a line to present a surface upon which the next line may be printed, and that after each line or portion of aline is completed by a step-bystep movement of the carriage the carriage 3o be returned to its initial ,position to begin another line of printing. All these movements of` the carriage and paper as well as the printing movement should be controlled automatically bythe movement of manually, mechanically, or electrically controlled means; and

it is the object of my present invention to provide mechanism for giving the required movements to the carriage, paper, and printing device by a means ofV simple yet efficient con- 4o struction and arrangement for such purposes.

The nature and scope of my invention willv be more fully understood from the following description, Vtaken in conjunction with the accompanying drawings, forming apart hereof,

in which- Figure 1 is a rear elevationalvview of such parts of a type-printing machine as are nec,- essary to illustrate and embody main features of my invention. Fig. 2 is an end elevational `View of Fig. l. Fig. 3 is a front elevational 5o view of the same. Fig. llis an enlarged horizontal sectional view on the line 4 4 of Fig. 1. Fig. 5 is an enlarged detail View illustrating in plan means for maintaining the paper-carriage in proper vertical position. Fig. 6 is a 55 detail view illustrating means for feeding the paper at the end of each line as Well as the means for shifting the paper and carriage by a step-by-step movement, and Fig. 7 is a detail view ofthe means for controlling the step- 6o by-step movement of the paper and carriage and the movement of the printing-hammer.

Referring to the drawings, a represents the framework of the type-prin ting machine, upon which is supported a rail a', preferably fixed. 65 Above the iixed rail a' is detachably supported a second rail c2. 'lheframe b of the papercarriage has at or near its base the Wheels b', riding upon the lower stationary rail a', and. above the Wheels b is arranged a cross-piece 7o b2, carrying two sets of brackets, whereof one set b3 carries horizontally-arranged wheels b4, inclosing the upper detachable rail CL2, and the other set of brackets b5 carries vertically-arranged wheels h6, engaging the under face of the rail a2. The Wheels b4, in conjunction with the Wheels h6 and wheels IJ and the two rails a and a2, serve to maintain the carriageframe b in proper vertical or operative position and at the same time permit the frame h 8o to shift laterally on the rails a and with scarcely any friction. To permit of the removal of the carriage and its frame l) from the machine, the detachable rail a2 may be lifted out of its supports by unloosening the end set-screws a3, whereupon the frame b and the auxiliary parts carried thereby can be lifted o the stationary rail a'. This construction is advantageous when it is necessary to quickly and easily remove the car- 9o riage for the purpose of repairing or cleansing the parts.

The frame b and the auxiliary parts carried thereby (which parts will be hereinafter more particularly described) are caused to shift laterally upon the rail a with a step-by-step collar or sleeve C73, around which is wound a rope or cord d4, one end of which is secured to a lever arm or key e. The other end of the cord d4 is depressed under the tension of a spring d5, connecting the cord to afixed part d of the'machine. The sleeve d3 carries an arm C77, to the free end of which is pivoted a pawl d8, engaging the notched periphery of a' ratchet-wheel C79, secured directly to the shaft d2. The lever arm or key e is normally held in depressed condition by means of a spring e', interposed between the key e and the framework of the machine. As clearly illustrated in Fig. 7, when the lever arm or key e is elevated to compress the spring e the cord d4 responds to its spring d5 and turns the sleeve C73, arm df, and pawl C78 around to the position indicated in dotted lines, the pawl c78 sliding over the notched periphery of the ratchetwheel df) without moving the same. When the key e is released, its spring e forces the key downward, the cord C74 being moved against its spring d5. The sleeve 73, arm d?, and pawl C78 are now returned to lthe normal position (indicated in full lines) and in turning operate or turn the ratchet-wheel 79, and consequently the shaft d2 and wormgear d. This movement of the shaft- (72 is sufficientto cause the gear d to advance the rack d a required distance or step. To prevent accidental movement of the shaft C72 or excessive response to the movement of the ratchet di), a detent d10 under tension of the spring d engages the toothed wheel C712, fixed to the shaft d2, as clearly illustrated in Fig. 6. As illustrated in the drawings, the upward movement of the key e is controlled by the energization of an'4 electromagnet e2.

While in electric type-printing instruments,

such as printing-telegraphs, such a means-of control is advantageous; yet it is obvious that the key e may be manually or mechanically controlled without departing from the spirit of my present invention.

As the carriage-frame 7') and auxiliaries are shifted step by step by the mechanism hereinbefore described, the line may be wholly or partly completed before `it is necessary to shift the carriage backward to its initial or starting point to begin a new line. When, however, the line is complete, the frame b and auxiliaries may be quickly'and easily returned by means of the following preferred mechanism: The frame 7) is advanced step by l' step against the tension of a spring j", nor-iy mally tending to return the frame 7) to its initial position. While the worm-gear 07 is',

in engagement with the rack c7 the springf can not shift the frame 79. Hence the gear d and rack c7 must first be brought out of mesh. To accomplish this, the shaft d2, with which the gear d turns, is mounted upon the upper or free ends of two rocking arms f. These arms f constitute` the sole bearings or supports for the shaft Pand its appurtenances, and their lower ends are connected together by a sleeve f2, oscillating upon a fixed shaft f3, properly supported by the frame of the machine. The sleeve f2 carries an arm or key g, normally under tension' of a spring g', which serves to throw the arms f forward to force the shaft C72 and gear d into operative relationship with the rack d. As illustrated in the drawings, an electromagnet g2 has its armature g3 secured to the key g and serves when energized to move said key against the tension of its spring g to thereby rock the arms f', so that the shaft d2 and worm c7 are drawn out of operative engagement with the rack d. It is, however, within the scope of my invention to replace the magnet g2 by suitable mechanical means, or, in fact, to so shape and arrange the key g that it'can' be readily manipulated by the hand of the operator. As soon as the worm d' has been withdrawn from the rack d the springfexerts its tension upon the frame b to shift said frame and auxiliaries to their initial position. The return of the frame b under tension of its springf may be checked by a suitable buffer f4.

In the drawings a type-printing machine has been illustrated wherein theprinting is done by forcing the paperA into contact with the periphery of a type-wheel A'. The means for controlling this type-wheel have not been illustrated, since such formsno part of my invention, and many well-known ways illustrated in the art may be used. The paper A is wound upon a roll 7i, mounted in the bearings 7L' in the frame b, these bearings 7L being adjustable by means of thumb-screws 71,2, so that the roll 7i may revolve with more or less freedom in the frame 7J. The paper A aft-er it leaves the roll 7i passes between two sets of feed-rollers h3 and 7t4,respectively, one set, 715, being positively driven by mechanism to be hereinafter described, whereas the other set, h4, is held frictionally down upon the paper by means of springs 715, as clearly illustrated in Fig. 2. After the paper A passes from the feed-rollers 713 and h4 it passes over a shieldplate 77., supported by the framework of the machine and which is interposed between the paper A and the periphery of the type-wheel A. A notch or slot 71,7 in the shield-plate h5 permits the proper portion of the `paper being forced against a type or character on thev type-wheel A' by means of a type-hammer fm.

This hammer m is supported upon the free end of a curved arm m', which is supported at its other end by a shaft m2, oscillating or rockin(r in trunnions m3 and m" one or both of which is or are made adjustable, being in the form of a set-screw. From the shaft m2 fore described. When this key e responds to the depressing action of its spring e, the rod mT drops and the hammer m and arm m are retracted by means of the spring m6 and rock-arm m5 to the position indicated in full lines in Fig. 2, Whereas when thekey e either i responds to the magnet e2 or is otherwise raised by mechanical or manual means the rod m7 is raised and the hammer fm strikes the paper A and forces it through the recess or slot 7LT into printing contact with the typesurface of the type-wheel A', as illustrated in dotted lines in Fig. 2. The feeding of the paper from the roll 7L is accomplished preferably when the carriage-frame and auxiliaries are shifted backward to their initial position under the influence of the springf. As illustrated in the drawings, the preferred means of accomplishing this result consists as foliows: The upper surface of the detachable rail a2 is provided with a series of teeth a4. The cross bar or piece 1221s provided with an upwardly-extending bracket o, in the upper end of which is pivoted one end of a downwardlyextending finger o', the free end of which engagesthe teeth a4 of the rail a2 and is shifted thereby from right to left when the carriageframe travels from left to right by a step-bystep movementand from left to right when the carriage-frame responds to its springf. As illustrated in detail in Fig. G, the pivot-pin o2 of the finger o carries the pins or projections o3, extending parallel to the face of the finger 0, and between these projections o3 extends a pin 04, projecting from an arm o5, loosely turning upon the shaft hs, connecting the feed-rollers 713. This arm o5 carries at its upper end a pawl o, arranged to slide over the periphery of a ratchet-wheel o8, secured to the shaft LS, when the arm o5 is raised by the movement of the finger o' and the projections o3 are controlled by the step-by-step movement of the carriage frame along the toothed rail a2. When, however, the arm o5 is depressed by the opposite movement of the finger o', it engages a tooth of the ratchet-wheel o8 and turns said wheel oS and shaft hs, 'and hence operates the feed-rollers r, which feed the paper A forward. For the purpose of inspecting the printing upon the paper A the upper part p of the carriage-frame b may be made separate from the lower part and hinged thereto, as at p', as illustrated in Figs. l, 2, and 3. Springs p2 normally keep the upper part p in alinement With the main frame b, but permit the upper part to be bent back with the paper away from the shield-plate 7L to inspect the printing.
